Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, ①which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. This flexibility allows companies ②to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs ③tailored precisely to individual patients, while automakers use it to build lightweight parts that reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lower the barrier to entry for entrepreneurs. As printing materials improve and machines become faster, the technology is expected ⑤to play an increasingly central role in future manufacturing.

Color plays a surprisingly powerful role in how consumers perceive brands, often shaping first impressions before a single word is read. Studies suggest that people form judgments about a product within seconds of seeing its packaging, and color accounts for a significant portion of that instant reaction. Blue, for instance, is frequently used by financial and technology companies because it tends to evoke feelings of trust and stability. Red, in contrast, ①are associated with energy and urgency, which ②explains why it appears so often in logos for fast-food chains. Marketers who ③ignore these cultural differences risk sending unintended messages to international audiences. For this reason, companies ④expanding into new markets often ⑤conduct extensive research before finalizing a logo's color scheme.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally ①swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, people forced to ②abandon their homes because of rising seas, droughts, or other disasters. This term, rarely used a decade ago, has become increasingly ③common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still ④manage to agree on how to protect people like her, since climate migrants are not officially ⑤recognized as refugees under current law.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ① governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ② suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③ promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④ out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤ heightened concentration, suggesting that timing matters as much as total sleep hours.

Anyone who has ridden a bicycle after a decade away from one has likely experienced muscle memory firsthand: the body seems to ① recall a complex skill almost instantly, even when conscious memory of the exact movements has faded. Contrary to what the name suggests, muscles themselves do not actually store memories; the phenomenon originates in the brain and nervous system, where repeated practice gradually ② hides control of a well-learned movement from regions associated with conscious thought to areas that operate largely automatically. This shift explains why a skilled athlete can execute a complicated sequence of movements without consciously thinking through each individual step, ③ freeing mental attention for strategy and decision-making instead. Interestingly, research also suggests that these neural pathways can remain ④ partially intact even after long periods without practice, which is why relearning a skill is typically much faster than learning it for the very first time. Coaches often exploit this principle by ensuring that fundamental techniques are practiced correctly from the very ⑤ beginning.

Imagine a cafeteria where a healthy salad sits at eye level while fried snacks rest on a low shelf. Nobody is forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics _______________. Companies and governments increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which persuades new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use. Unlike strict regulations or heavy taxes, nudges rely on subtle changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability.

The filter bubble does not stay limited to search results; it gradually shapes nearly every aspect of a person's online experience. (A) For instance, a user who frequently watches cooking videos may find that recommended content across multiple platforms becomes overwhelmingly food-related within just a few days. (B) As this pattern continues, the same user may rarely encounter unrelated topics, such as political news or scientific discoveries, unless algorithms judge them relevant. (C) Streaming services, shopping websites, and news aggregators all rely on similar algorithms that learn from previous clicks and viewing habits.

Not all parts of a city experience the same temperature, even when they are located close to one another. (A) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. (B) To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. (C) On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling.

주어진 문장: After all, ignoring proven facts might seem like an irrational thing to do. When people encounter solid scientific evidence about climate change, we might expect them to accept it without hesitation. ( ① ) However, many individuals still dismiss or downplay such evidence, and psychologists explain this pattern through a concept called motivated reasoning. ( ② ) Motivated reasoning refers to the tendency to process information in a way that protects one's existing beliefs, identity, or lifestyle rather than to pursue objective truth. ( ③ ) For example, a person whose livelihood depends on the fossil fuel industry may unconsciously search for reasons to doubt climate data, even while claiming to value scientific accuracy. ( ④ ) This happens because accepting uncomfortable facts can threaten a person's sense of self or demand costly lifestyle changes. ( ⑤ ) Therefore, simply presenting more data rarely persuades a committed skeptic. Instead, experts suggest connecting climate information to values the person already holds, such as family safety or economic stability, so that acceptance feels natural rather than threatening.
